Secondary glazing supplied and fitted by Andrews Glass in Hertfordshire

Secondary Glazing in Hertfordshire

If you want to reduce noise, improve comfort and keep your original windows, secondary glazing gives you an internal barrier without changing the external appearance of your property.

Andrews Glass supply and fit secondary glazing across Hertfordshire for homes, period properties, listed buildings, sash windows and commercial premises. It is a practical choice when you want better noise reduction, improved insulation or more comfort without replacing the original windows. Based in Sawbridgeworth, we have been trusted locally for over 50 years for glass, glazing, windows and doors.

Want Better Comfort Without Replacing Your Original Windows?

Do you live with draughty windows, outside noise, cold rooms or older frames that you do not want to remove? Maybe the property has historic character, original sash windows, conservation restrictions or a front elevation you do not want to change.

  • Road noise, traffic or general outside noise getting into the room
  • Cold spots and draughts around older windows
  • Original windows that are part of the property character
  • Listed building or conservation concerns
  • High upfront cost of full window replacement
  • Concern about damaging original frames or changing the external appearance

We understand. In many properties, full window replacement is not the best or most sensitive option. Secondary glazing creates an independent internal barrier behind the existing window, helping improve comfort while preserving the outside appearance and original frames.

Why Choose Secondary Glazing Over Full Window Replacement?

You would choose secondary glazing over full window replacement or standard double glazing when you want to preserve historic character, reduce noise more effectively, avoid changing the outside appearance, or keep upfront costs lower.

Before Secondary Glazing

  • Original windows letting in cold and noise
  • Rooms that are harder to heat or relax in
  • Concern about replacing windows on an older property
  • External appearance that needs to stay unchanged

After Secondary Glazing

  • An internal glazing layer added behind the original window
  • Better sound reduction and improved comfort
  • Original frames and external appearance retained
  • A practical alternative to full window replacement

Secondary Glazing FAQs

What is secondary glazing?

Secondary glazing is an additional pane or glazing system fitted internally behind an existing window. It creates a separate barrier that can improve noise reduction, insulation and comfort without changing the outside appearance of the building.

Why choose secondary glazing instead of double glazing?

Secondary glazing is often chosen when you want to keep the original windows, preserve historic character, reduce noise, avoid external changes, or reduce upfront cost compared with full replacement windows.

Is secondary glazing good for listed buildings?

Secondary glazing can be a good option for listed buildings and conservation properties because it is fitted internally and does not usually change the external appearance. You may still need to check any planning or conservation requirements for your property.

Can secondary glazing reduce road noise?

Yes. Secondary glazing can be very effective for reducing road noise, traffic noise and other outside disturbance because it creates an independent internal barrier behind the original window.

Does secondary glazing help with heat loss?

Yes. Secondary glazing can help reduce heat loss, draughts and cold spots by adding an extra layer between the room and the existing window.

Will secondary glazing damage my original windows?

Secondary glazing is designed to work with the existing window rather than replace it. The right fitting method will depend on the frame, opening and property, and Andrews Glass can advise on the most suitable approach.
